For this year's Record Store Day, the surviving members of Soundgarden have teamed with singer Brandi Carlile to record new versions of "Black Hole Sun" and "Searching With My Good Eye Closed."

The tribute to late Soundgarden vocalist Chris Cornell will be released as a 12-inch on September 26th, part of a three-day Record Store Day celebration that was reconfigured after the pandemic scrapped the regular late April event.

The songs were recorded at Seattle's London Bridge Studio, a legendary place that hosted both Soundgarden and Carlile early in their careers, along with many other Seattle music luminaries.

Carlile wrote about recording her early demos there with her band, saying, "Soundgarden were just gods to us back then. Total pioneers and unreachable to us in every way. We went about making our demos and cleaning the studio when we couldn't afford the bill never knowing that in November of 2019 we would go back to London Bridge and RECORD TWO SONGS WITH THEM!!"

Carlile posted a number of pictures from the studio, as well as a video of Soundgarden's Kim Thayil shredding through a guitar solo.
